SumoSprings - The Airless Air Spring

The more you load the more they resist. Sumo Springs reduce sag, bounce, sway and bottoming out with a closed cell polyurethane foam airless air spring.

SumoSprings are designed to maximize the GVWR of the vehicle. Like other helper spring kits, they will not increase the GVWR or the carrying capacity of your truck, but SumoSprings will help maintain your truck’s level attitude, and enhance the ride and handling.

SumoSprings - Engineered for Tough Environments

SumoSprings are made of an advanced high grade, closed cell polyurethane foam that is ideal for the tough truck underbody environment. Sumosprings have been tested in extreme conditions ranging from blistering desert summer days with the U.S. Border Patrol to the frigid Canadian winter nights.
